Paging opportunity monitoring

ABSTRACT

This disclosure provides systems, methods, and apparatuses for wireless communication. A user equipment (UE) may acquire a triggering synchronization signal block (SSB), which enables the UE to monitor for a floating Type-2 physical downlink control channel (PDCCH) and to determine a subset of paging occasions (POs) to monitor. Or, the UE may monitor for a fixed Type-2 PDCCH, where the UE does not require a triggering signal to monitors POs. In another aspect, the UE may monitor for a paging transmission during a monitoring period. The UE may determine the monitoring period based on received signaling. The UE may receive the signaling, during the monitoring period, indicating that the monitoring period is to be ended before a scheduled end of the monitoring period. In this way, the UE may support a continuity requirement associated with downlink reference signaling (DRS) and may support reception of paging in a shared channel.

TECHNICAL FIELD

Aspects of the present disclosure generally relate to wirelesscommunication, and more particularly to techniques and apparatuses forpaging opportunity monitoring.

DESCRIPTION OF THE RELATED TECHNOLOGY

Wireless communication systems are widely deployed to provide varioustelecommunication services such as telephony, video, data, messaging,and broadcasts. Typical wireless communication systems may employmultiple-access technologies capable of supporting communication withmultiple users by sharing available system resources (for example,bandwidth, transmit power, etc.). Examples of such multiple-accesstechnologies include code division multiple access (CDMA) systems, timedivision multiple access (TDMA) systems, frequency-division multipleaccess (FDMA) systems, orthogonal frequency-division multiple access(OFDMA) systems, single-carrier frequency-division multiple access(SC-FDMA) systems, time division synchronous code division multipleaccess (TD-SCDMA) systems, and Long Term Evolution (LTE).LTE/LTE-Advanced is a set of enhancements to the Universal MobileTelecommunications System (UMTS) mobile standard promulgated by theThird Generation Partnership Project (3GPP).

A wireless communication network may include a number of base stations(BSs) that can support communication for a number of user equipment(UEs). A user equipment (UE) may communicate with a base station (BS)via the downlink (DL) and uplink (UL). The DL (or forward link) refersto the communication link from the BS to the UE, and the UL (or reverselink) refers to the communication link from the UE to the BS. As will bedescribed in more detail herein, a BS may be referred to as a NodeB, anLTE evolved nodeB (eNB), a gNB, an access point (AP), a radio head, atransmit receive point (TRP), a New Radio (NR) BS, or a 5G NodeB.

The above multiple access technologies have been adopted in varioustelecommunication standards to provide a common protocol that enablesdifferent user equipment to communicate on a municipal, national,regional, and even global level. NR, which also may be referred to as5G, is a set of enhancements to the LTE mobile standard promulgated bythe Third Generation Partnership Project (3GPP). NR is designed tobetter support mobile broadband Internet access by improving spectralefficiency, lowering costs, improving services, making use of newspectrum, and better integrating with other open standards using OFDMwith a cyclic prefix (CP) (CP-OFDM) on the DL, using CP-OFDM or SC-FDM(for example, also known as discrete Fourier transform spread OFDM(DFT-s-OFDM)) on the UL (or a combination thereof), as well assupporting beamforming, multiple-input multiple-output (MIMO) antennatechnology, and carrier aggregation.

SUMMARY

The systems, methods and devices of this disclosure each have severalinnovative aspects, no single one of which is solely responsible for thedesirable attributes disclosed herein.

One innovative aspect of the subject matter described in this disclosurecan be implemented in a method of wireless communication performed by anapparatus of a user equipment (UE). The method may include determining aplurality of resource locations associated with a Type-2 physicaldownlink control channel (PDCCH) transmission, where the Type-2 PDCCH isa floating Type-2 PDCCH or a fixed Type-2 PDCCH; and monitoring theresource location to attempt to receive the Type-2 PDCCH.

In some aspects, a configuration of the Type-2 PDCCH defaults to aconfiguration of a Type-0 PDCCH. In some aspects, the Type-2 PDCCH isassociated with a common core resource set with a Type-0 PDCCH. In someaspects, a monitoring period for the monitoring is defined based atleast in part on at least one of: a timer expiration for the Type-2PDCCH, a detection of one or more Type-0 PDCCH core resource sets(CORESETs) without a paging radio network temporary identifier (P-RNTI),or a detection of a Type-2 PDCCH CORESET with a P-RNTI.

In some aspects, the Type-2 PDCCH occurs during or after a downlinkreference signal (DRS) transmission period. In some aspects, the methodmay include triggering a paging monitoring timer associated with amonitoring period for the monitoring based at least in part on detectionof a DRS transmission. In some aspects, the method may include detectingthe DRS transmission based at least in part on at least one of asynchronization signal block detection, a Type-0 PDCCH detection, or aType-2 PDCCH detection.

In some aspects, a monitoring period for the monitoring is defined withrespect to a Type-0 PDCCH transmission that is detectable based at leastin part on at least one of a CORESET demodulation reference signal(DMRS) parameter, a remaining minimum system information (RMSI)allocation parameter, or a synchronization signal block (SSB) detectionparameter.

In some aspects, a monitoring period for the monitoring is defined withrespect to a Type-2 PDCCH transmission that is detectable based at leastin part on at least one of a CORESET DMRS parameter, a paging radionetwork temporary identifier (P-RNTI) allocation parameter, or an SSBdetection parameter.

In some aspects, the monitoring includes monitoring for the Type-2 PDCCHbased at least in part on a quasi-co-location (QCL) relationship for theType-2 PDCCH. In some aspects, the resource location associated with theType-2 PDCCH is associated with a fixed mapping QCL relationship. Insome aspects, the Type-2 PDCCH is associated with a same slot as a SSBor is offset from the SSB by a particular period of time. In someaspects, the particular period of time is defined based at least in parton a stored period or a configured period.

In some aspects, the resource location of the Type-2 PDCCH is associatedwith a particular set of candidate QCL locations. In some aspects, theparticular set of candidate QCL locations are restricted based at leastin part on at least one of a repetition period, an offset value, or amonitoring duration with respect to a detected synchronization signalblock or a time value derived from a system timing.

In some aspects, the resource location of the Type-2 PDCCH is associatedwith a QCL location at each Type-2 PDCCH opportunity within a monitoringwindow associated with a monitoring period for the monitoring. In someaspects, a downlink control information (DCI) of the Type-2 PDCCHindicates a k0 parameter value identifying a subsequent allocation for aphysical downlink shared channel (PDSCH) carrying a paging message. Insome aspects, a Type-2 PDSCH is associated with a k0 parameter tableidentifying a set of k0 parameters for allocations after a DRS thatsatisfy at least one of an occupied channel bandwidth (OCB) requirement,a continuity requirement, or a capacity requirement.

In some aspects, the OCB requirement is at least one of a requirementfor different wideband QCL allocations that are time-divisionmultiplexed (TDM) or a requirement for different narrowband WCLallocations that are frequency division multiplexed (FDM). In someaspects, a monitoring period for the monitoring is associated withmultiple paging occasion windows (POWs) in each DRS transmission period.

In some aspects, multiple of Type-2 PDCCH CORESET candidates are mappedwithin a single channel occupancy time (COT). In some aspects, each ofmultiple Type-2 PDSCH allocations for paging occupies symbols betweentwo successive Type-2 PDCCH CORESET candidates. In some aspects, a DCImessage in the Type-2 PDCCH or a Type-2 PDCCH allocation includes anindicator of whether additional Type-2 PDCCH allocations with a same QCLparameter are to be provided and a location of the additional Type-2PDCCH allocations.

In some aspects, the Type-2 PDCCH is associated with a telescopingType-2 PDCCH CORESET map and a mapping is selected for COT pagingcompactness. In some aspects, a telescoping Type-2 PDCCH CORESET maprefers to a set of Type-2 PDCCH CORESET candidates with a same QCLparameter. In some aspects, a monitoring period for the monitoring isdetermined based at least in part on a paging COT continuity constraintassociated with a paging capacity requirement. In some aspects, amonitoring period for the monitoring is defined based at least in parton an early termination timer. In some aspects, the UE is configured tostop monitoring QCL Type-2 PDCCH candidates when a termination timer hasexpired and after a signal associated with DRS. In some aspects, themonitoring includes detecting the Type-2 PDCCH without having detected aDRS.

In some aspects, the monitoring includes monitoring for the Type-2 PDCCHafter a downlink reference signal is detected. In some aspects, the UEmay end the monitoring for the Type-2 PDCCH based at least in part onnot detecting paging before an expiration of an early termination timeror before an expiration of a paging monitoring window. In some aspects,the UE may determine a paging configuration. In some aspects, the UE maymonitor based at least in part on the paging configuration.

In some aspects, the paging configuration is at least one of aDRS-conditional POW with a set of possible start and length indicatorvalues, a DRS-conditional POW with a threshold periodicity, a pagingwindow with a set of possible international mobile subscriber identity(IMSI) messages, a low-capacity paging configuration, or, ahigh-capacity paging configuration. In some aspects, determining thepaging configuration includes determining the paging configuration basedat least in part on at least one of a radio resource control (RRC)paging message, an RRC information element (IE), a DCI flag associatedwith a paging radio network temporary identifier (RNTI), a DCI flagassociated with a system information radio network temporary identifier(SI-RNTI), or a physical broadcast channel (PBCH) flag. In some aspects,determining the paging configuration includes switching from ahigh-capacity paging configuration to a low-capacity pagingconfiguration based at least in part on at least one of a timerexpiration or a triggering message.

Another innovative aspect of the subject matter described in thisdisclosure can be implemented in a UE for wireless communication. The UEmay include memory and one or more processors operatively coupled to thememory. The memory and the one or more processors may be configured todetermine a plurality of resource locations associated with a Type-2PDCCH transmission, where the Type-2 PDCCH is a floating Type-2 PDCCH ora fixed Type-2 PDCCH; and monitor the resource location to attempt toreceive the Type-2 PDCCH.

Another innovative aspect of the subject matter described in thisdisclosure can be implemented in a non-transitory computer-readablemedium. The non-transitory computer-readable medium may store one ormore instructions for wireless communication. The one or moreinstructions, when executed by one or more processors of a UE, may causethe one or more processors to determine a plurality of resourcelocations associated with a Type-2 PDCCH transmission, where the Type-2PDCCH is a floating Type-2 PDCCH or a fixed Type-2 PDCCH; and monitorthe resource location to attempt to receive the Type-2 PDCCH.

In some aspects, the paging transmission is associated with a PDCCH. Insome aspects, the resource location is at least one of a startingresource location for the monitoring period or a stopping resourcelocation for the monitoring period. In some aspects, the signaling is atleast one of a system information radio network temporary identifier(SI-RNTI)-scrambling of a downlink control information (DCI), a pagingradio network temporary identifier (P-RNTI)-scrambling of a DCI, a DCI,a DCI explicitly carrying the signaling, a DCI implicitly indicating thesignaling, a channel occupancy time start signal, or a channel occupancytime end signal.

In some aspects, the signaling includes at least one of a flagidentifying whether paging is to be further monitored in the monitoringperiod, a bitmap indicating a set of UEs to which the signaling applies,a change to a DCI configuration, a starting time for monitoring for apaging DCI, a resource indication for monitoring for a paging DCI, aperiodicity identifier for the paging transmission, a payload message, apaging message, or a SI-RNTI scrambling. In some aspects, the method mayinclude receiving further signaling during monitoring of the monitoringperiod and selectively monitoring in accordance with the furthersignaling. In some aspects, selectively monitoring in accordance withthe further signaling includes continuing to monitor based on thesignaling indicating that further paging is to be transmitted. In someaspects, selectively monitoring in accordance with the further signalingincludes ending monitoring based on the signaling indicating thatfurther paging is not to be transmitted.

In some aspects, the further signaling is at least one of aSI-RNTI-scrambled DCI, a P-RNTI-scrambled DCI, a DCI, a physical signal,or a monitored signal. In some aspects, the monitoring period may be asingle contiguous interval. In some aspects, the monitoring period maybe a plurality of disjointed intervals. In some aspects receiving thesignaling includes receiving signaling during the monitoring period. Insome aspects, the method may include determining, based at least in parton the signaling identifying the resource location of the end of themonitoring period, that the paging transmission is not to occur at atime subsequent to receiving the signaling; and monitoring, during themonitoring period, for the paging transmission may include ending themonitoring period.

DETAILED DESCRIPTION

The following description is directed to certain implementations for thepurposes of describing the innovative aspects of this disclosure.However, a person having ordinary skill in the art will readilyrecognize that the teachings herein can be applied in a multitude ofdifferent ways. Some of the examples in this disclosure are based atleast in part on wireless and wired local area network (LAN)communication according to the Institute of Electrical and ElectronicsEngineers (IEEE) 802.11 wireless standards, the IEEE 802.3 Ethernetstandards, and the IEEE 1901 Powerline communication (PLC) standards.However, the described implementations may be implemented in any device,system or network that is capable of transmitting and receiving radiofrequency signals according to any of the wireless communicationstandards, including any of the IEEE 802.11 standards, the Bluetooth®standard, code division multiple access (CDMA), frequency divisionmultiple access (FDMA), time division multiple access (TDMA), GlobalSystem for Mobile communications (GSM), GSM/General Packet Radio Service(GPRS), Enhanced Data GSM Environment (EDGE), Terrestrial Trunked Radio(TETRA), Wideband-CDMA (W-CDMA), Evolution Data Optimized (EV-DO),1×EV-DO, EV-DO Rev A, EV-DO Rev B, High Speed Packet Access (HSPA), HighSpeed Downlink Packet Access (HSDPA), High Speed Uplink Packet Access(HSUPA), Evolved High Speed Packet Access (HSPA+), Long Term Evolution(LTE), AMPS, or other known signals that are used to communicate withina wireless, cellular or internet of things (IOT) network, such as asystem utilizing 3G, 4G or 5G, or further implementations thereof,technology.

In New Radio (NR), a downlink reference signal (DRS) continuityrequirement may be established. For example, a BS may continuouslytransmit a DRS in a single channel occupancy time (COT). To maintaincontinuity, the BS may multiplex remaining minimum system information(RMSI) and synchronization signal block (SSB) transmissions. Forexample, an RMSI physical downlink control channel (PDCCH) may be timedivision multiplexed with an SSB or an RMSI physical downlink sharedchannel (PDSCH) may be frequency division multiplexed (FDM) with an SSB.In this way, the BS may ensure a compact, continuous DRS. Further, theBS may transmit paging information and other system information (OSI)transmissions in a common COT with a DRS.

To achieve the continuous DRS requirement, the BS may transmit using aset of SSB candidates when the BS obtains access to transmissionresources using, for example, a contention-based access procedure, suchas a listen-before-talk (or listen-before-transmit, LBT) procedure.Further, to achieve the continuous DRS requirement, the UE may beenabled to monitor multiple paging occasion (PO) candidates of a pagingoccasion window (POW) at a fixed location or based at least in part on aflexible mapping of detected DRSs or known quasi-co location (QCL)relationships to floating or fixed PO candidate locations. Some aspectsdescribed herein provide for floating position monitoring and fixedposition monitoring for UE or for paging opportunity monitoring. Forexample, a UE may determine a resource location for a Type-2 PDCCH, suchas a floating Type-2 PDCCH or a fixed Type-2 PDCCH, and may monitor toattempt to receive the Type-2 PDCCH. As another example, a UE mayreceive signaling identifying a resource location and may monitor for apaging transmission during a monitoring occasion. In someimplementations, the monitoring occasion may be determined based on thesignaling.

Particular implementations of the subject matter described in thisdisclosure can be implemented to realize one or more of the followingpotential advantages. For example, the UE may enable the BS to satisfythe DRS continuity requirement, may enable an efficient utilization ofnetwork resources and may enable flexibility with regard to utilizationof network resources. Moreover, the UE and the BS may enable increasednetwork flexibility with regard to support by enabling different typesof PDCCH configurations or different types of UE configurations to bedeployed in a network, as described in more detail herein. Furthermore,by enabling a dynamically indicated starting condition, stoppingcondition, or duration for a monitoring period, the UE may reduceutilization of power resources relative to starting a monitoring periodbefore paging is to be performed or relative to remaining in amonitoring period after further paging is not to be performed.Furthermore, back-to-back transmission of DRS and paging messages,enabled by increasing a quantity of paging candidates for the BS toselect, enables the BS to limit shared spectrum utilization byaggregating the DRS, paging, or other signals into a singletransmission.

FIG. 1 is a block diagram conceptually illustrating an example of awireless network 100. The wireless network 100 may be an LTE network orsome other wireless network, such as a 5G or NR network. Wirelessnetwork 100 may include a number of BSs 110 (shown as BS 110 a, BS 110b, BS 110 c, and BS 110 d) and other network entities. A BS is an entitythat communicates with user equipment (UEs) and also may be referred toas a base station, a NR BS, a Node B, a gNB, a 5G node B (NB), an accesspoint, or a transmit receive point (TRP). Each BS may providecommunication coverage for a particular geographic area. In 3GPP, theterm “cell” can refer to a coverage area of a BS, a BS subsystem servingthis coverage area, or a combination thereof, depending on the contextin which the term is used.

A BS may provide communication coverage for a macro cell, a pico cell, afemto cell, another type of cell, or a combination thereof. A macro cellmay cover a relatively large geographic area (for example, severalkilometers in radius) and may allow unrestricted access by UEs withservice subscription. A pico cell may cover a relatively smallgeographic area and may allow unrestricted access by UEs with servicesubscription. A femto cell may cover a relatively small geographic area(for example, a home) and may allow restricted access by UEs havingassociation with the femto cell (for example, UEs in a closed subscribergroup (CSG)). A BS for a macro cell may be referred to as a macro BS. ABS for a pico cell may be referred to as a pico BS. A BS for a femtocell may be referred to as a femto BS or a home BS. In the example shownin FIG. 1 , a BS 110 a may be a macro BS for a macro cell 102 a, a BS110 b may be a pico BS for a pico cell 102 b, and a BS 110 c may be afemto BS for a femto cell 102 c. A BS may support one or multiple (forexample, three) cells. The terms “eNB”, “base station”, “NR BS”, “gNB”,“TRP”, “AP”, “node B”, “5G NB”, and “cell” may be used interchangeablyherein.

In some examples, a cell may not necessarily be stationary, and thegeographic area of the cell may move according to the location of amobile BS. In some examples, the BSs may be interconnected to oneanother as well as to one or more other BSs or network nodes (not shown)in the wireless network 100 through various types of backhaulinterfaces, such as a direct physical connection, a virtual network, ora combination thereof using any suitable transport network.

Wireless network 100 also may include relay stations. A relay station isan entity that can receive a transmission of data from an upstreamstation (for example, a BS or a UE) and send a transmission of the datato a downstream station (for example, a UE or a BS). A relay stationalso may be a UE that can relay transmissions for other UEs. In theexample shown in FIG. 1 , a relay station 110 d may communicate with amacro BS 110 a and a UE 120 d in order to facilitate communicationbetween the macro BS 110 a and the UE 120 d. A relay station also may bereferred to as a relay BS, a relay base station, a relay, etc.

A wireless network 100 may be a heterogeneous network that includes BSsof different types, for example, macro BSs, pico BSs, femto BSs, relayBSs, etc. These different types of BSs may have different transmit powerlevels, different coverage areas, and different impacts on interferencein the wireless network 100. For example, macro BSs may have a hightransmit power level (for example, 5 to 40 Watts) whereas pico BSs,femto BSs, and relay BSs may have lower transmit power levels (forexample, 0.1 to 2 Watts).

A network controller 130 may couple to a set of BSs and may providecoordination and control for these BSs. The network controller 130 maycommunicate with the BSs via a backhaul. The BSs also may communicatewith one another, for example, directly or indirectly via a wireless orwireline backhaul.

UEs 120 (for example, 120a, 120b, 120c) may be dispersed throughout thewireless network 100, and each UE may be stationary or mobile. A UE alsomay be referred to as an access terminal, a terminal, a mobile station,a subscriber unit, a station, etc. A UE may be a cellular phone (forexample, a smart phone), a personal digital assistant (PDA), a wirelessmodem, a wireless communication device, a handheld device, a laptopcomputer, a cordless phone, a wireless local loop (WLL) station, atablet, a camera, a gaming device, a netbook, a smartbook, an ultrabook,a medical device or equipment, biometric sensors/devices, wearabledevices (smart watches, smart clothing, smart glasses, smart wristbands, smart jewelry (for example, smart ring, smart bracelet)), anentertainment device (for example, a music or video device, or asatellite radio), a vehicular component or sensor, smart meters/sensors,industrial manufacturing equipment, a global positioning system device,or any other suitable device that is configured to communicate via awireless or wired medium.

Some UEs may be considered machine-type communication (MTC) or evolvedor enhanced machine-type communication (eMTC) UEs. MTC and eMTC UEsinclude, for example, robots, drones, remote devices, sensors, meters,monitors, location tags, etc., that may communicate with a base station,another device (for example, remote device), or some other entity. Awireless node may provide, for example, connectivity for or to a network(for example, a wide area network such as Internet or a cellularnetwork) via a wired or wireless communication link. Some UEs may beconsidered Internet-of-Things (IoT) devices or may be implemented asNB-IoT (narrowband internet of things) devices. Some UEs may beconsidered a Customer Premises Equipment (CPE). A UE 120 may be includedinside a housing that houses components of the UE 120, such as processorcomponents, memory components, similar components, or a combinationthereof.

In general, any number of wireless networks may be deployed in a givengeographic area. Each wireless network may support a particular RAT andmay operate on one or more frequencies. A RAT also may be referred to asa radio technology, an air interface, etc. A frequency also may bereferred to as a carrier, a frequency channel, etc. Each frequency maysupport a single RAT in a given geographic area in order to avoidinterference between wireless networks of different RATs. In some cases,NR or 5G RAT networks may be deployed.

In some examples, access to the air interface may be scheduled, where ascheduling entity (for example, a base station) allocates resources forcommunication among some or all devices and equipment within thescheduling entity's service area or cell. Within the present disclosure,as discussed further below, the scheduling entity may be responsible forscheduling, assigning, reconfiguring, and releasing resources for one ormore subordinate entities. That is, for scheduled communication,subordinate entities utilize resources allocated by the schedulingentity.

Base stations are not the only entities that may function as ascheduling entity. That is, in some examples, a UE may function as ascheduling entity, scheduling resources for one or more subordinateentities (for example, one or more other UEs). In this example, the UEis functioning as a scheduling entity, and other UEs utilize resourcesscheduled by the UE for wireless communication. A UE may function as ascheduling entity in a peer-to-peer (P2P) network, in a mesh network, oranother type of network. In a mesh network example, UEs may optionallycommunicate directly with one another in addition to communicating withthe scheduling entity.

Thus, in a wireless communication network with a scheduled access totime-frequency resources and having a cellular configuration, a P2Pconfiguration, and a mesh configuration, a scheduling entity and one ormore subordinate entities may communicate utilizing the scheduledresources.

In some aspects, two or more UEs 120 (for example, shown as a UE 120 aand a UE 120 e) may communicate directly using one or more sidelinkchannels (for example, without using a base station 110 as anintermediary to communicate with one another). For example, the UEs 120may communicate using peer-to-peer (P2P) communications,device-to-device (D2D) communications, a vehicle-to-everything (V2X)protocol (which may include a vehicle-to-vehicle (V2V) protocol, avehicle-to-infrastructure (V2I) protocol, or similar protocol), a meshnetwork, or similar networks, or combinations thereof. In this case, theUEs 120 may perform scheduling operations, resource selectionoperations, as well as other operations described elsewhere herein asbeing performed by the base station 110.

FIG. 2 is a block diagram conceptually illustrating an example 200 of abase station 110 in communication with a UE 120. In some aspects, thebase station 110 and the UE 120 may respectively be one of the basestations and one of the UEs in the wireless network 100 of FIG. 1 . Thebase station 110 may be equipped with T antennas 234 a through 234 t,and the UE 120 may be equipped with R antennas 252 a through 252 r,where in general T≥1 and R≥1.

At the base station 110, a transmit processor 220 may receive data froma data source 212 for one or more UEs, select one or more modulation andcoding schemes (MCS) for each UE based at least in part on channelquality indicators (CQIs) received from the UE, process (for example,encode and modulate) the data for each UE based at least in part on theMCS(s) selected for the UE, and provide data symbols for all UEs. Atransmit processor 220 also may process system information (for example,for semi-static resource partitioning information (SRPI), etc.) andcontrol information (for example, CQI requests, grants, upper layersignaling, etc.) and provide overhead symbols and control symbols. Thetransmit processor 220 also may generate reference symbols for referencesignals (for example, the cell-specific reference signal (CRS)) andsynchronization signals (for example, the primary synchronization signal(PSS) and secondary synchronization signal (SSS)). A transmit (TX)multiple-input multiple-output (MIMO) processor 230 may perform spatialprocessing (for example, precoding) on the data symbols, the controlsymbols, the overhead symbols, or the reference symbols, if applicable,and may provide T output symbol streams to T modulators (MODs) 232 athrough 232 t. Each modulator 232 may process a respective output symbolstream (for example, for OFDM, etc.) to obtain an output sample stream.Each modulator 232 may further process (for example, convert to analog,amplify, filter, and upconvert) the output sample stream to obtain adownlink signal. T downlink signals from modulators 232 a through 232 tmay be transmitted via T antennas 234 a through 234 t, respectively.According to various aspects described in more detail below, thesynchronization signals can be generated with location encoding toconvey additional information.

At the UE 120, antennas 252 a through 252 r may receive the downlinksignals from the base station 110 or other base stations and may providereceived signals to demodulators (DEMODs) 254 a through 254 r,respectively. Each demodulator 254 may condition (for example, filter,amplify, downconvert, and digitize) a received signal to obtain inputsamples. Each demodulator 254 may further process the input samples (forexample, for OFDM, etc.) to obtain received symbols. A MIMO detector 256may obtain received symbols from all R demodulators 254 a through 254 r,perform MIMO detection on the received symbols if applicable, andprovide detected symbols. A receive processor 258 may process (forexample, demodulate and decode) the detected symbols, provide decodeddata for UE 120 to a data sink 260, and provide decoded controlinformation and system information to a controller or processor(controller/processor) 280. A channel processor may determine referencesignal received power (RSRP), received signal strength indicator (RSSI),reference signal received quality (RSRQ), channel quality indicator(CQI), etc. In some aspects, one or more components of the UE 120 may beincluded in a housing.

On the uplink, at the UE 120, a transmit processor 264 may receive andprocess data from a data source 262 and control information (forexample, for reports including RSRP, RSSI, RSRQ, CQI, etc.) from acontroller/processor 280. The transmit processor 264 also may generatereference symbols for one or more reference signals. The symbols fromthe transmit processor 264 may be precoded by a TX MIMO processor 266 ifapplicable, further processed by the modulators 254 a through 254 r (forexample, for DFT-s-OFDM, CP-OFDM, etc.), and transmitted to the basestation 110. At the base station 110, the uplink signals from the UE 120and other UEs may be received by the antennas 234, processed by thedemodulators 232, detected by a MIMO detector 236 if applicable, andfurther processed by a receive processor 238 to obtain decoded data andcontrol information sent by the UE 120. The receive processor 238 mayprovide the decoded data to a data sink 239 and the decoded controlinformation to a controller or processor (controller/processor) 240. Thebase station 110 may include a communication unit 244 and communicate toa network controller 130 via the communication unit 244. The networkcontroller 130 may include a communication unit 294, a controller orprocessor (controller/processor) 290, and a memory 292.

While subsequent paragraphs may refer to Type-2 PDCCH, pagingallocations and corresponding monitoring windows, PDSCHs, andcandidates, it will be understood that the same descriptions apply toother broadcast allocations, such as Type-0A PDCCH and OSI (Other SystemInformation) allocations.

The controller/processor 240 of the base station 110, thecontroller/processor 280 of the UE 120, or any other component(s) ofFIG. 2 may perform one or more techniques associated with Type-2 PDCCHmonitoring, as described in more detail elsewhere herein. For example,the controller/processor 240 of the base station 110, thecontroller/processor 280 of the UE 120, or any other component(s) (orcombinations of components) of FIG. 2 may perform or direct operationsof, for example, a process 800 of FIG. 8 , process 1000 of FIG. 10 , orother processes as described herein. The memories 242 and 282 may storedata and program codes for the base station 110 and the UE 120,respectively. A scheduler 246 may schedule UEs for data transmission onthe downlink, the uplink, or a combination thereof.

The stored program codes, when executed by the controller/processor 280or other processors and modules at the UE 120, may cause the UE 120 toperform operations described with respect to the process 800 of FIG. 8 ,process 1000 of FIG. 10 , or other processes as described herein. Ascheduler 246 may schedule UEs for data transmission on the downlink,the uplink, or a combination thereof.

In some aspects, UE 120 may include means for determining a plurality ofresource locations associated with a Type-2 PDCCH transmission, and theType-2 PDCCH is a floating Type-2 PDCCH or a fixed Type-2 PDCCH; meansfor monitoring the resource location to attempt to receive the Type-2PDCCH; or combinations thereof. In some aspects, UE 120 may includemeans for receiving signaling identifying a resource location of atleast one of a start or an end of a monitoring period for a pagingopportunity, means for monitoring, during the monitoring period, for apaging transmission associated with the paging opportunity based on theat least one of the start or the end of the monitoring period, orcombinations thereof. In some aspects, such means may include one ormore components of the UE 120 described in connection with FIG. 2 .

While blocks in FIG. 2 are illustrated as distinct components, thefunctions described above with respect to the blocks may be implementedin a single hardware, software, or combination component or in variouscombinations of components. For example, the functions described withrespect to the transmit processor 264, the receive processor 258, the TXMIMO processor 266, or another processor may be performed by or underthe control of controller/processor 280.

FIG. 3 is a diagram illustrating an example 300 of monitoring a floatingType-2 PDCCH. As shown in FIG. 3 , example 300 may include a BS 110 anda UE 120.

As shown in FIG. 3 , and by reference number 310, the UE 120 maydetermine a resource location for a Type-2 PDCCH transmission. Forexample, when the UE 120 is to monitor for a floating Type-2 PDCCH, theUE 120 may determine, based at least in part on stored configurationinformation, that the Type-2 PDCCH is defaulted to a Type-0 PDCCH. Inthis case, the Type-2 PDCCH may be associated with a same controlresource set (CORESET) as the Type-0 PDCCH and may include a pagingradio network temporary identifier (P-RNTI) allocation in each Type-2PDCCH. In some aspects, the UE 120 may determine a stopping conditionfor ending a monitoring period during which the UE 120 is to monitor forthe Type-2 PDCCH. For example, the UE 120 may determine to stopmonitoring for the Type-2 PDCCH after a timer expiration, afterdetection of a Type-0 PDCCH, such as a Type-0 PDCCH that includes anSI-RNTI (system information radio network temporary identifier)scrambling or a Type-2 PDCCH includes a P-RNTI scrambling. In this case,the UE 120 may determine the stopping condition based at least in parton receipt of, for example, a paging DCI and a stop flag aggregated intoa single control and/or data message.

A PDCCH candidate location may be classified as floating if at least oneparameter (which may include timing) is dependent on detection of aprior signal (e.g. QCL mapping is dependent on a time of a DRS or an SSBwith the same QCL). A PDCCH candidate location may be classified asfixed if parameters (which may include timing) can be determined frominformation already known or configured for the UE. For example, thetime of a candidate quasi co-located with a particular SSB can bedetermined from a cell common (system information block (SIB) or masterinformation block (MIB)) configuration, rather than requiringinformation of an immediately prior DRS transmission. In floating PDCCHmonitoring, the UE 120 may receive triggering information identifying atime or a configuration for monitoring. In fixed PDCCH monitoring, theUE 120 may monitor without having received triggering informationidentifying the time or the configuration for monitoring when triggeredto monitor.

In some aspects, the UE 120 may determine a resource location formonitoring a floating Type-2 PDCCH candidate based at least in part on aquasi-co-location (QCL) relationship between the Type-2 PDCCH and a veryrecently detected DRS transmission. For example, the Type-2 PDCCH may beassociated with a fixed mapping relationship in which the Type-2 PDCCHis associated with a same slot as an SSB transmission. In this case, fora floating Type-2 PDCCH, the floating Type-2 PDCCH may be a triggeredfloating Type-2 PDCCH when monitoring starts immediately after receivingthe DRS transmission. In contrast, a fixed Type-2 PDCCH candidate may bea configured fixed Type-2 PDCCH when monitoring starts on a periodicbasis using QCL relationships derived from a past transmission (whichmay be a downlink reference signal (DRS) or another broadcast or unicastsignal). As shown by reference numbers 320 and 330, the BS 110 maytransmit, and the UE 120 may monitor to receive the Type-2 PDCCHcandidates, which may be time division multiplexed (TDM) with a set ofSSB candidates. In some aspects, the BS 110 may forgo transmission ofone or more SSB candidates. Even if some SSB candidates are nottransmitted in a particular DRS occasion, the UE 120 may still monitorpaging candidates based on QCL relationships with the SSB candidateswith which the UE 120 is configured from prior transmissions. In someaspects, configured windows may be used for monitoring both fixed andfloating Type-2 PDCCH candidates. For monitoring of floating candidates,the UE 120 may receive a start signal to trigger the monitoring.

FIG. 4 is a diagram illustrating an example 400 of monitoring a floatingType-2 PDCCH based on DRS triggering. As shown in FIG. 4 , the example400 may include a BS 110 and a UE 120. Although some aspects aredescribed in terms of floating Type-2 PDCCH being based on animmediately prior DRS transmission, other aspects may have fixed Type-2PDCCH monitoring based on configured monitoring windows, as describedabove. In each case, Type-2 PDCCH may have a plurality of PDCCHcandidates quasi co-located with SSBs, and the UE 120 may monitor in awindow (or a plurality of windows), which may repeat.

As shown in FIG. 4 , and by reference number 410, the UE 120 maydetermine a resource location for a Type-2 PDCCH transmission. Forexample, when the UE 120 is to monitor for a floating Type-2 PDCCH, theUE 120 may determine, based at least in part on stored configurationinformation, that the Type-2 PDCCH is to occur with or after one or moreType-0 PDCCHs of a DRS transmission period. In this case, the UE 120 maydetermine that the Type-2 PDCCH is to occur with, or after the DRStransmission period, during the DRS transmission period.

As further shown in FIG. 4 , and by reference numbers 420 and 430, theBS 110 may transmit, and the UE 120 may monitor to receive the Type-2PDCCHs, which may be time division multiplexed (TDM) with a set of SSBcandidates. In some aspects, the UE 120 may activate a paging monitoringtimer to determine a monitoring period for attempting to receive aType-2 PDCCH. For example, when a DRS is detected, the UE 120 maytrigger a timer countdown, and may attempt to detect the Type-2 PDCCHbefore expiration of the timer countdown. In some aspects, the BS 110may transmit a Type-2 PDCCH after a Type-0 PDCCH. Alternatively, the BS110 may transmit the Type-2 PDCCH without having transmitted the Type-0PDCCH.

In some aspects, the UE 120 may detect a DRS transmission that triggersa monitoring period for attempting to receive the Type-2 PDCCH based atleast in part on detecting another transmission. For example, the UE 120may detect an SSB transmission, and may detect the DRS transmissionbased at least in part on detecting the SSB transmission. Additionally,or alternatively, the UE 120 may detect a Type-0 PDCCH transmission andmay detect the DRS transmission based at least in part on detecting theType-0 PDCCH transmission.

In some aspects, the UE 120 may detect the Type-0 PDCCH transmissionbased at least in part on another parameter. For example, the UE 120 maydetect the Type-0 PDCCH transmission based at least in part on aparameter relating to a CORESET demodulation reference signal (DMRS),such as whether a signal to interference noise ratio (SINR) is greaterthan or equal to 6 decibels (dB). Additionally, or alternatively, the UE120 may detect the Type-0 PDCCH based at least in part on a remainingminimum system information (RMSI) allocation, such as a systeminformation RNTI (SI-RNTI) or a non-P-RNTI transmission, which the UE120 may use to validate a system information RNTI (SI-RNTI).Additionally, or alternatively, the UE 120 may detect the Type-0 PDCCHbased at least in part on a P-RNTI allocation, which the UE 120 may useto validate a P-RNTI cyclic redundancy check (CRC); a detection of anSSB transmission. Additionally, or alternatively, the UE 120 may detectthe Type-0 PDCCH based at least in part on a configured monitoringcandidate location, such as based at least in part on a serving DRSmeasurement timing configuration (DMTC), which the UE 120 may use forcell camping evaluation.

In some aspects, the UE 120 may determine a resource location forreceiving a floating Type-2 PDCCH based at least in part on aquasi-co-location (QCL) relationship between the Type-2 PDCCH and adetected DRS transmission. For example, the Type-2 PDCCH may beassociated with a fixed mapping relationship in which the Type-2 PDCCHis associated with a fixed time offset or a configured time offsetrelative to an SSB transmission. Additionally, or alternatively, the UE120 may monitor a selected subset of QCL locations that are restrictedin accordance with a repetition period parameter, an offset parameter,or a monitoring duration parameter and are determined based at least inpart on an SSB transmission or with respect to an absolute time value.In this way, by monitoring multiple candidate QCL locations, the UE 120enables different paging capacities with a floating Type-2 PDCCH andaccounts for COT location uncertainty in a shared medium. In someaspects, the UE 120 may monitor all Type-2 PDCCH opportunities, such asthose which occur within a monitoring period defined with respect to apaging monitoring timer, thereby improving flexibility of pagingconfigurations. In some cases, the UE 120 may monitor Type-2 PDCCHopportunities without information identifying associated QCLrelationships.

In some aspects, the UE 120 may determine, based at least in part onstored information, a set of fixed PO candidates, such as multiple POcandidates in each DRX cycle. In this case, the UE 120 may receivepaging signals associated with the set of fixed PO candidates in adifferent COT or in a same COT as a DRS. For example, the UE 120 mayreceive paging signals associated with the set of fixed PO candidates ina single continuous COT using a QCL relationship determined based atleast in part on an occurrence of a cyclic wraparound. In this case, theUE 120 may be provisioned with one or more POWs in each DRS in which tomonitor for the set of fixed PO candidates of the single continuous COT.

FIG. 5 is a diagram illustrating an example 500 of PDCCH candidates in apaging channel occupancy time (COT). As shown in FIG. 5 , example 500includes a BS 110 and a UE 120.

As further shown in FIG. 5 , and by reference number 510, the UE 120 maydetermine a resource location for a Type-2 PDCCH transmission. Forexample, when the UE 120 is to monitor for a floating Type-2 PDCCH or afixed Type-2 PDCCH, the UE 120 may map Type-2 PDCCH CORESETs compactlyto a single slot, to a set of contiguous slots, or to a set ofdisjointed slots within a single COT. In this case, as shown byreference numbers 520 and 530, the BS 110 may transmit, and the UE 120may monitor to receive the Type-2 PDCCHs and subsequent paging PDSCHs.

In some aspects, a resource allocation for the BS 110 and the UE 120 maylack a set of physical resource blocks in an SSB slot for allocation toa PDSCH that conveys a paging message. In this case, the BS 110 mayprovide a Type-2 PDCCH DCI with a k0 parameter that points to asubsequent resource allocation in a common COT. For example, the BS 110may provide RRC signaling to identify an allocation list and aconfiguration for the subsequent resource allocation for the PDSCH.Additionally, or alternatively, the UE 120 may use a default signalingtable, thereby obviating a need for explicit signaling. For example, thedefault signaling table may include information identifying a set of k0parameter options for allocations after a DRS. Further, the defaultsignaling table may include information identifying a set of k0parameter options for satisfying an occupied channel bandwidth (OCB)requirement, a continuity requirement, as described above, or a capacityrequirement. In this case, the OCB requirement may relate to havingdifferent wideband QCL allocations, such as greater than 16 megahertz(MHz), that are time division multiplexed (TDM), may relate to havingdifferent narrowband QCL allocations that are frequency divisionmultiplexed (FDM). In this way, the default signaling table may ensurethat the OCB requirement is satisfied.

In some aspects, the UE 120 may be provisioned with a particular startand length indicator value table. For example, UE 120 may use a startand length indicator value table that allows allocations for PDSCHs tooccur in a reverse order of Type-2 PDCCH occurrence. For example, asshown, a first Type-2 PDCCH, occurring before a listen-before-talk (LBT)occasion is complete, may correspond to a last paging PDSCH occasion.Similarly, a second Type-2 PDCCH may correspond to a second to lastpaging PDSCH occasion, and so on. In some aspects, when a CORESET failsfor the LBT occasion, the BS 110 may drop corresponding PDSCHs of theLBT occasion.

In some aspects, the UE 120 may receive a P-RNTI scrambling, whichindicates that additional P-RNTI allocations are to be expected. In someaspects, an indication may be transmitted in a control channel, such asvia a Type-2 PDCCH, in a payload channel, such as via a PDSCH allocatedby a Type-2 PDCCH message. In some aspects, the indication may includean indication of a location of an additional subsequent allocation thatis to occur or may indicate to the UE 120 to select a subsequent P-RNTIallocation opportunity based at least in part on stored or internalconfiguration. In this case, such indications may inform the UE 120 ofQCL relationships between Type-2 PDCCH candidates to monitor.

In some aspects, the UE 120 may be configured to ignore a subset offuture Type-2 PDCCH candidate occasions in the monitoring window, whendetecting the successful reception of a current Type-2 PDCCH candidate.In this case, the UE 120 may still continue monitoring subsequent Type-2PDCCH candidates that satisfy one or more configured criteria, such asnot being subject to a known PDSCH allocation or being subject toacquired information to expect the reception of subsequent Type-2 PDCCHcandidate.

FIG. 6 is a diagram illustrating an example 600 of PDCCH candidates in apaging COT. As shown in FIG. 6 , the example 600 may include a BS 110and a UE 120.

As further shown in FIG. 6 , and by reference number 610, the UE 120 maydetermine a resource location for a Type-2 PDCCH transmission associatedwith a telescoping Type-2 CORESET map. In this case, the BS 110 mayselect a map, of a set of candidate maps, based at least in part on acompactness criterion for a paging COT. For example, when the UE 120 isto monitor for a floating Type-2 PDCCH or a fixed Type-2 PDCCH, the BS110 may map Type-2 PDCCH CORESETs compactly to a subsequent Type-2PDSCH. In this case, as shown by reference numbers 620 and 630, the BS110 may transmit, and the UE 120 may monitor to receive the Type-2PDCCHs and subsequent Type-2 PDSCHs.

In some aspects, the BS 110 may transmit Type-2 PDCCH candidates in apaging COT based at least in part on a paging capacity criterion for thepaging COT and to satisfy a continuity constraint for the paging COT. Inthis case, the UE 120 may lack QCL relationship-based informationidentifying which Type-2 PDCCH occasion the BS 110 will use fortransmission. As a result, in some aspects, the UE 120 may monitor allpossible Type-2 PDCCH occasions to receive the Type-2 PDCCH candidatesfrom the BS 110.

FIG. 7 is a diagram illustrating an example 700 of monitoring both afloating Type-2 PDCCH and a fixed Type-2 PDCCH. As shown in FIG. 7 , theexample 700 includes a BS 110 and a UE 120.

As further shown in FIG. 7 , and by reference number 710, the UE 120 maydetermine a resource location for a Type-2 PDCCH transmission. In thiscase, the UE 120 may be configured to detect the Type-2 PDCCH withouthaving detected a DRS. In some aspects, the UE 120 may determine tomonitor for a Type-2 PDCCH after a DRS is detected in accordance with anearly termination timer. Additionally, or alternatively, the UE 120 maydetermine to monitor for the Type-2 PDCCH during an entirety of a POW.As shown by reference numbers 620 and 630, the BS 110 may transmit, andthe UE 120 may monitor to receive the Type-2 PDCCHs and subsequentType-2 PDSCHs.

In some aspects, as shown in Case I, when a paging PDSCH is receivedafter a DRS, the UE 120 may monitor for a particular period of timeafter the DRS to receive Type-2 PDCCHs. In this case, the UE 120 mayterminate monitoring at the end of an early termination timer in both afirst sub-scenario (i.e., where the UE 120 does not condition monitoringon detecting a DRS), which may be termed DRS-unaware, and in a secondsub-scenario (i.e., where the UE 120 does condition monitoring ondetecting a DRS), which may be termed DRS-aware. In some aspects, the UE120 may enable an early termination timer immediately after a paging DCIis detected to enable termination of monitoring at the end of the earlytermination timer.

In contrast, as shown in Case II, when no paging is received after aDRS, a DRS-aware UE 120 may terminate at expiration of the earlytermination timer, but a DRS-unaware UE 120 may not terminate until anend of a POW. In this way, the UE 120 may be provisioned to accommodatemultiple different use cases. In some aspects, the BS 110 may signal anabsence of paging using a DRS, and the UE 120 may terminate monitoringfor paging based at least in part on receiving the DRS, thereby savingpower relative to waiting until expiration of an early termination timerto terminate monitoring for paging.

In some aspects, such as when the UE 120 is provisioned with multiplepaging configurations, the UE 120 may determine one of the multiplepaging configurations to use for determining a monitoring period fordetecting a Type-2 PDCCH, or a subsequent PDSCH. For example, the UE 120may be configured with a DRS-conditional POW, a limited start and lengthindicator flexibility paging configuration, a high periodicity pagingconfiguration, or a low-capacity paging configuration. In this case, thelow-capacity paging configuration may enable less than a threshold, suchas less than three, international mobile subscriber identity (IMSI)identities in the paging message. Additionally, or alternatively, the UE120 may be configured with a high-capacity paging configuration thatenables greater than or equal to a threshold quantity of, for example,IMSI messages. In some aspects, the UE 120 may switch from thelow-capacity paging configuration to the high-capacity pagingconfiguration, as described herein. For example, the UE 120 may switchbetween the multiple paging configurations based at least in part on aradio resource control (RRC) paging message, an RRC information element(IE) message, a DCI flag of a P-RNTI, a DCI flag of an SI-RNTI, or aflag of a physical broadcast channel (PBCH). In this case, the UE 120may fall back from the high-capacity paging configuration to thelow-capacity paging configuration based at least in part on expirationof a timer, receipt of a triggering message, such as an RRC message or aDCI flag.

FIG. 8 is a diagram illustrating an example process 800 performed, forexample, by a UE, in accordance with various aspects of the presentdisclosure. Example process 800 is an example where a UE, such as the UE120, performs operations associated with Type-2 PDCCH monitoring.

As shown in FIG. 8 , in some aspects, process 800 may includedetermining a plurality of resource locations associated with a Type-2PDCCH transmission and the Type-2 PDCCH is a floating Type-2 PDCCH or afixed Type-2 PDCCH (block 810). For example, the UE (using receiveprocessor 258, transmit processor 264, controller/processor 280, ormemory 282) may determine a plurality of resource locations associatedwith a Type-2 PDCCH transmission and the Type-2 PDCCH is a floatingType-2 PDCCH or a fixed Type-2 PDCCH, as described above. In someaspects, the Type-2 PDCCH is a floating Type-2 PDCCH or a fixed Type-2PDCCH.

As further shown in FIG. 8 , in some aspects, process 800 may includemonitoring the plurality of resource locations to attempt to receive theType-2 PDCCH (block 820). For example, the UE (using receive processor258, transmit processor 264, controller/processor 280, or memory 282)may monitor the plurality of resource locations to attempt to receivethe Type-2 PDCCH, as described above.

In atwenty-second aspect, alone or in combination with one or more of thefirst through twenty-first aspects, a DCI message in the Type-2 PDCCH ora Type-2 PDCCH allocation includes an indicator of whether additionalType-2 PDCCH allocations with a same QCL parameter are to be providedand a location of the additional Type-2 PDCCH allocations.

In a twenty-third aspect, alone or in combination with one or more ofthe first through twenty-second aspects, the Type-2 PDCCH is associatedwith a telescoping Type-2 PDCCH CORESET map and a mapping is selectedfor COT paging compactness.

Although FIG. 8 shows example blocks of process 800, in some aspects,process 800 may include additional blocks, fewer blocks, differentblocks, or differently arranged blocks than those depicted in FIG. 8 .Additionally, or alternatively, two or more of the blocks of process 800may be performed in parallel.

FIG. 9 is a diagram illustrating an example 900 of paging occasionmonitoring. As shown in FIG. 9 , the example 900 includes a BS 110 and aUE 120.

As shown in FIG. 9 , and by reference number 910, the UE 120 may receivecontrol signaling from the BS 110. For example, the UE 120 may receivecontrol signaling identifying a resource location, such as a start of amonitoring period for a paging occasion or an end to a monitoring periodfor a paging occasion. In this case, the UE 120 may lack a prioriinformation identifying the start of the monitoring period or the end ofthe monitoring period before receiving the control signaling, or may beconfigured with a different start of the monitoring period or end of themonitoring period. In some aspects, the monitoring period may be asingle continuous interval. In some aspects, the monitoring period maybe multiple disjoint, or disjointed, intervals.

In some aspects, the control signaling may indicate a resource locationfor a paging opportunity start or a DRS monitoring window start. In someaspects, the UE 120 may receive control signaling identifying a start ofa monitoring period, an end of a monitoring period, or a criterion foraltering the monitoring period. In some implementations, the UE 120 mayreceive control signaling identifying the end of the monitoring periodduring the monitoring period itself.

In some aspects, the UE 120 may be triggered to start the monitoringperiod based on receiving a SI-RNTI scrambled DCI, a P-RNTI DCI, oranother type of RNTI-scrambled DCI. Additionally, or alternatively, theUE 120 may be triggered to start the monitoring period based onreceiving control signaling indicating a start of a COT or another typeof physical signal.

In some aspects, the UE 120 may parse the control signaling to determinethe monitoring period. For example, the UE 120 may determine that alower layer signal, such as a DCI, includes a flag indicating that apaging message is to occur at a subsequent time or that a paging messageis not to occur at a subsequent time. Additionally, or alternatively,the UE 120 may determine that a bitmap in the control signalingindicates that the control signaling applies to the UE 120 or one ormore other UEs. Additionally, or alternatively, the UE 120 may determinea k0 parameter or a periodicity based on the control signaling.

In some aspects, the UE 120 may parse a payload of the control signalingto determine a monitoring period. For example, the UE 120 may receiveRRC paging, a SIB message, or a paging message including an indicator ofwhether paging messages are to occur during a monitoring period. In someaspects, the UE 120 may receive a paging message and may determine notto monitor for subsequent paging during a threshold period of time.Alternatively, the UE 120 may receive the paging message or a P-RNTI DCIand may determine that an allocation for paging is to be received at asubsequent time.

As further shown in FIG. 9 , and by reference number 920, the UE 120 maydetermine a monitoring period for a paging opportunity. For example, theUE 120 may determine to start a monitoring period to monitor for pagingat a current time or at a subsequent time based on the controlsignaling. Additionally, or alternatively, the UE 120 may determine toend a currently ongoing monitoring period at a current time or at asubsequent time based on the control signaling. In some aspects, the UE120 may determine to continue monitoring until a stopping criterion isdetected, such as an SI-RNTI based DCI detection occurring.

As further shown in FIG. 9 , and by reference number 930, the UE 120 maymonitor during the monitoring period to attempt to receive the paging.For example, the UE 120 may monitor for paging during a particularperiod of time and may end monitoring for paging at a particular periodof time determined based on the monitoring period. As an example, the UE120 may receive an SI-RNTI DCI indicating that new paging is not tooccur and may stop the monitoring period before a configured end to themonitoring period. As another example, the UE 120 may end the monitoringperiod after receiving a P-RNTI during the monitoring period thatincludes paging and an indication that further paging is not to occur.As another example, the UE 120 may end the monitoring period afterdetecting a CORESET type 0 in connection with an SI-RNTI DCI but notdetecting a P-RNTI DCI.

In some aspects, the UE may include a first interface forreceiving the signaling.

As shown in FIG. 10 , in some aspects, process 1000 may includemonitoring, during the monitoring period, for a paging transmissionassociated with the paging opportunity based on the at least one of thestart or the end of the monitoring period (block 1020). For example, theUE (using receive processor 258, transmit processor 264,controller/processor 280, memory 282) may monitor, during the monitoringperiod, for a paging transmission associated with the paging opportunitybased on the at least one of the start or the end of the monitoringperiod.

In a fifth aspect, alone or in combination with any one or more of thefirst through fourth aspects, the process 1000 may include receivingfurther signaling during monitoring of the monitoring period andselectively monitoring in accordance with the further signaling.

In a sixth aspect, alone or in combination with any one or more of thefirst through fifth aspects, selectively monitoring in accordance withthe further signaling includes continuing to monitor based on thesignaling indicating that further paging is to be transmitted.

In a seventh aspect, alone or in combination with any one or more of thefirst through sixth aspects, the further signaling is at least one of aSI-RNTI-scrambled DCI, a P-RNTI-scrambled DCI, a DCI, a physical signal,or a monitored signal.
